Washington, April 4 : Japanese researchers suggest that periodontal disease may act as a risk factor for reactivating latent HIV-1 in affected individuals.

Scientists from Tokyo-based Nihon University highlight the fact that latently infected cells harbour HIV-1 proviral DNA genomes integrated with heterochromatins, allowing for the persistence of transcriptionally silent proviruses.

Washington, Apr 4: Late-night shift work may increase the risks of developing cancer, says a new study.

According to Tulane University expert Dr. David Blask, late-night exposure to light may diminish levels of a natural cancer-fighting hormone.

Washington, Apr 4: Nursing mothers’ breast milk might one day help assess future breast cancer risk, say researchers.

A research team led by environmental toxicologist Kathleen Arcaro of the University of Massachusetts Amherst will be conducting a series of experiments to identify methylated genes that indicate potentially pre-cancerous changes in breast cells.

The test could show signs of elevated breast cancer risk in women at an earlier age than ever before.

London, Apr 4: Researchers at Monash University’s Centre of Cardiovascular Research and Education in Therapeutics have developed a new catheter-based therapy that can be an effective alternative for lowering high blood pressure when medication fails.

The new surgical technique disrupts nerves around the kidneys to dramatically reduce high blood pressure.

Washington, Apr 4: Kids born to parents under stress—induced by low income, having little education, and being a single parent—are more likely to have tooth decay, according to a study.

Researchers from The Ohio State University examined the stress levels of parents whose young children either had no cavities or so many cavities that they had to receive anaesthesia before undergoing dental treatment.

The team looked the parents'' education levels and income, and noted whether they were single parents.

Washington, Apr 4: A new study from Norwegian Institute of Public Health (NIPH) has revealed that mothers with many negative thoughts and feelings are likely to give unhealthy food to their kids.

The researchers have found that mothers who were emotionally unstable, anxious, angry, sad, had poor self-confidence or a negative view of the world were far more likely to give their child sweet and fatty foods.
